Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609874, here are decompositions:

41 + 8609833 = 8609874
61 + 8609813 = 8609874
83 + 8609791 = 8609874
101 + 8609773 = 8609874
191 + 8609683 = 8609874
197 + 8609677 = 8609874
211 + 8609663 = 8609874
223 + 8609651 = 8609874

Showing the first eight; more decompositions exist.
